Superb post Steve_Seattle. And if all the critics wanted what was best for the child then they would condemn adoption by homosexuals.
I think that is completely and totally wrong.
Do you think doctors should refuse to treat smokers?
Now, there is a little bit of truth in the "worldview" part - if a person with an infection doesn't believe in germs, for example.
But if I didn't treat anyone who didn't share my basic values and worldview, I'd be out of business, and if you post here frequently, so would you.
